Tuning might fix your issue. You will need to increase the lockup mph and rpm in the computer. If as mentioned above that the TCC is not disengaging, then this should be an issue in all gears. Vince

It may be doing it in all the gears, but is much more noticable in OD/4th.

I have a big cam, so its not as prolific down bottom?
